There is 4-6 bolt hole, by bolt, adapter sleeve is fixed in rotating shaft, and then ring seal set is fixed on
In rotating shaft, ring seal set is made to rotate along with the rotation of rotating shaft.
Described stationary ring sealing shroud is by upper sealing ring and is enclosed within the rubber sleeve outside upper sealing ring and forms, upper sealing ring
Being formed by Ti alloy casting, its lower surface processes through polishing, and smoothness is high, and service life is long；Rubber sleeve
Lateral surface is provided with external screw thread, it is simple to fixing upper sealing ring.
Described spring is provided with several, equidistant is arranged between lower sealing ring and adapter sleeve, and balancing force is big,
Can make that the sealing surface between upper sealing ring with lower sealing ring is combined is more tight, when self-aligning bearing is beated,
It is not result between sealing surface occurring gap, it is therefore prevented that the generation of oil leakage phenomenon.
The beneficial effects of the utility model are: upper sealing ring and lower seal are formed by Ti alloy casting, table on it
Face processes through polishing, and smoothness is high, and ring good airproof performance, service life is long.Lower sealing ring and adapter sleeve it
Between be provided with several spring, balancing force is big, and the sealing surface between upper sealing ring with lower sealing ring can be made to be combined more
Add closely, it is therefore prevented that the generation of oil leakage phenomenon.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model.
